    摘要： A method is disclosed for producing a hollow body by cold spraying. A mold core is used for producing the hollow body, the mold core being prepared for the production of the hollow body by cold spraying in a suitable manner by means of an auxiliary layer. The auxiliary layer may include or consist of a metallic material and therefore forms a suitable surface to which the particles processed by cold spraying remain adhered to form the hollow body. The mold core can therefore be produced from an inexpensive material such as sand or wood, although said materials are in principle have limited suitability for depositing metals by cold spraying. The auxiliary layer can be applied to the mold core as a foil, or be produced on the mold core by cold-spraying low-melting and/or soft materials, for example.

    摘要： A method for forming a part. The method includes: forming a first portion of the part at a first level; forming a second portion of the part at a second level; wherein forming the first and second portions includes exposing the first and second levels to a sintering process and portions of the first and second levels to an electron beam; forming a wire in the passage formed inside the first and second portions by exposing a portion of the passage to the electron beam; applying a signal to the wire to break up sintered material in the passage; and removing the wire.

    摘要： A process for fabricating hollow metal shells such as Be or Al filled with a selected gas such as D or T. An organic preform is coated with a slurry of organic binder and metal powder of Be or Al. The coated preform is heated to remove the preform and any organics to form a hollow shell which is then fired at an elevated temperature in a gas so as to seal the shell and capture the gas inside the sealed shell.
